Redirect dns resolution based source ip

Hi Team,

I need help

I need to iRules for redirect dns resolution based source ip/subnet for which weighted ratio LB method configured under pool for WIDE IP

Sample: rule:

when DNS_REQUEST {

if { [IP::addr [IP::client_addr] equals 10.10.10.0/24] } {

use pool GTM_pool1

} else {

cname www.redirect.domain.com

}

}

 In above example, instead of pointing to pool(GTM Pool1), want to point to Destination IP.

Thanks in advance
